矿井爆破采煤工艺技术的几点探讨

Discussion on mine blasting mining technology

爆破采煤工艺的特点是采用爆破方法落煤,在一些开采机械化水平较低的中小型矿井中应用广泛,爆破采煤仍是主要的开采方式。爆破落煤的要求有:炮眼角度、炮眼间距、炮眼深度、炮眼装药量。爆破操作及安全注意事项:打眼时的安全注意事项、连线方式与爆破段长度、爆破注意事项。

The characteristics of blasting coal mining process are that coal is removed by blasting method.It is widely used in small and medium-sized mines with low level of mechanization for mining.Blasting is still the main method of mining.The requirements for blasting coal are as follows:blasthole angle,blasthole spacing,blasthole depth,and blasthole charge.Blasting operation and safety precautions:safety precautions,connection methods,blasting section length,and blasting precautions when drilling.
